M5Stack Gray Dev Kit 1.0 with Mac Catalina



  • I am trying to get the ports to appear with Arduino when I attached the M5Stack Gray Dev unit. I have installed the Silicon Labs later drivers (CP210x) and confirm they work. (Ports appear when I connect other ESP32 based devices). However, when I connect M5Stack, I only see "/dev/cu.Bluetooth-Incoming-Port" and I am unable to connect to the device.

    When I connect a M5StickC it works fine.

    Has anyone has success getting the Core dev kit working with Mac Catalina (10.15.17).
    Any suggestions on how to resolve this?

    Hello, could you try to install FTDI drivers as well to see if it can solve the issue for you?
